IMPROVEMENT IN BARVB-FENCE MACHINES.

Specfi cation forming part of Letters Patent No. 222,608, dated December 1G, 1879; application filed August 19, 1879.

To all whom it may concern:

Be it known that I, SIDNEY M. STEVENS, of De Kalb, in the county of De Kalb and State of Illinois, have invented certain new and useful Improvements in Barb-Fence Machines, of which the following is a specification.

In the accompanying drawings, which form a part of this specification, Figures 1 and 2 are plan or top views ofthe machine, showing 1t with the mechanism in dierent positions. Fig. 3' is a side elevation of the machinein the condition shown by the plan, Fig. 1. Fig. 4 is a like view of themachine in the position shown at Fig. 2. The Figs. 3 and Aare partly in section. Fig. 5 is a detail view, in elevation, of the barbwre feed-rollers. Fig. 6 is a similar view of the barb-Wire cutters.

I purpose using, in connection with this machine, any suitable apparatus for spooling or twisting and spooling the barbed ,wire with which my mechanism to be hereinafter described will co-operate in combination; but I have not deemed it necessary to do more in this than show the gearing at A A A2 A3 A4, which connects such twisting, or twisting and spooling, devices with the mechanism for applyingbarbs that is the subject of the present invention.

Any person skilled in these matters may understand how to apply and combine the two mechanisms, the gearing being indicated.

In the drawings, B represents a suitable frame-work, upon which the various parts and devices are mounted in their proper relation and position.

G is a carriage constructed to slide back and forth upon suitable ways on themain frame B. A regular reciprocating motion is imparted to this carriage by means of the crank-shaft D and one or more pitmen, E, which connect said crank-shaft with the carriage. i

Mounted upon the carriage, and standing with its axis parallel to the line of motion of the carriage, is the barb-coiling cylinder F. Through this cylinder, which is constructed in the ordinary fashion of barb-coiling cylinders, the main fence-wires G pass longitudinally. Said coilingcylinder F is furnished with a bevel-pinion, F', which engagesthe large bevel-gear wheel H, which is also mounted on the carriage, and which has its axis at right anratchet, J, and the pawl is carried in a swinging arm, J', suspendedfrom the shaft H' of gage the teeth of the ratchet J. i

The arm J', which carries the pawl K, is connected by a pivoted tie-rod, L, to the main or stationary frame-work B of the machine, so that at each forward motion of the carriage (motion to the left hand of the drawings) the pawl engages the ratchet and rotates the wheel with a partial revolution in the direction of the arrows, which is sufficient to impart to the coiling-cylinder t-he required rotation.

In the backward motion of the carriage the pawl is drawn into position without moving the wheel H 5 consequently, during the backward` motion of the carriage the coiling-cylinder does not rotate. l

By this arrangement and combination I obtain the necessary movement of the coilingcylinder with a proper timing and all necessary speed, with a comparatively slow movement of the'gearing always in one direction, and obbackward motion of the carriage. Of course, it will be understood that a single revolution of the wheel H applies several barbs. In the instance shown in the drawings, one revolution of said wheel applies six barbs; and it will be readily seen that, by changing the proportion, a still greater number could be applied during a single revolution.

In order to prevent the momentum of the wheel carrying it pa-st the required position, l prefer to apply a series of stop-pins, m, which, in the forward motion of the carriage and forward rotation of the wheel, successively encounter the stop-plate M, extending up from the frame of the machine and over the carriage. This device insures that the coilingcylinder shall stop always in a proper position` to receive the barb-wire which is fed into it.

The barbed wire is passed between a pair of sition at the coiling-cylinder. The action of gearing is made in the form of along-toothed y the wheel H J. KV is a pawl, contrived to e11- tain a period of rest of the gearing during the y horizontal feed-rolls, N N, which feed it forward through the knife-block into proper poi these feed-rolls is intermittent, and timed to accord with the motion of the coiling-cylinder, so that the barb-wire is fed into the coilingcylinder during the retreat of .the carriage.

The rolls N N are geared together by gears N' N', and are act-uated by a pawl, N2, and ratchet a, which is connected, by a jointed and pivoted tie-rod, N3, to a stationary part of the Y machine in such manner that the motion of the carriage actuates the feed-rolls intermit! tends down below the machine, and imparts motion to the knife at the proper time, as follows: The roller Q', at the lower end of saidl lever, strikes,`in the forward motion of the carriage, against 'a stop, It, fixed to the framework of the. machine, and the carriage moving onward causes the lever to retract the knife, as will be readilyunderstood, and as indicated in Figs.'3 and 6. The backward motion of the carriage carries this same roller into contact with the cam S on the shaft S', actuated by Athe gears S2 S3, in the manner indicated in Fig. 4. This cam S, being constantly in motion through said gearing from the shaft B, forces forward the end of the lever Q at the properinstant-'t'. c., when the carriage nears the end of its retreat-and causes the knives to operate to sever the barb-wire by pushing forward the movable blade and its carryingblock. 1

It will be noticed that in this machine not only does the cylinder move with the main wire forward in the act of coiling the barb upon it, so that said main wire may, if desired, be fed continuously through the machine, but that also all the other necessary coacting parts of the barbing mechanism--namely, the feed for the barb-wire, and the knives for cutting olf the barb-move with it upon the same carriage. This, of course, simplilies the structure greatly, and at the same time tends to make the timing and intervals more accurate and uniform,

and less liable to derangement. It will also be noticed that the machine moves with a deliberate action, without sudden and violent stopping and starting, and without more motion of the parts than is necessary to accomplish the work. It will also be understood that the barb-feeding device, timed,'as it is, to operate during the retreat of the carriage, and the cutting devices also operating at this movement, and moving with the carriage, saves time and obviates the necessity of any pause in theL motion of the machine for allowing the barb to be fed in.

I claim- 1. In a machine for applying barbs to fencewire, the combination of a barb-feeding device, a barb-cutting device, a barb-coiling device for coilin g the barb upon the main wires, and a reciproeatin g carriage upon which all of said devices are mounted, substantially as speciiie'd.

2. The combination, with the moving carriage, of the coiling-cylinder and` its pinion, the large gear-wheel and the pawl for actuating the same, connected by a pivoted tierod to the stationary part ofthe machine, substantially1 -as specified. .l .i

3. The combination of the reciprocating carriage, intermittent gear-wheel, coiling-cylinA der and pinion, barb-cutters, and feed-rolls with a crank-shaft and pitman for imparting a reciprocating movement to said carriage, substantially as specified.

4. The device for operating the barb-cntt-ers, consisting of a lever pivoted'to the moving carriaga also to the moving blade of the cutters, and extending below in a position to beoperated upon by the stop R and cam S, and said stop and said cam, substantially as specified.

5. In a machine for applying barbs to fencewire, the combination of a barb-feeding device, a-barb-cutting device, and a device for coiling the bar-b'upon the fence-wire, all reciprocating in line with the fence-wire, and moving simultaneously in such reciprocation, and means for imparting such reciprocation, substantially as specified.

6. In a machine for applying barbs to fencewire, the combination of a"barbfeeding device, a barb-cutting device, and a device for coiling the barb upon the fence-wire, all reciprocating simultaneously, and timed to operate substantially as specified, to wit: the coiling device during the advance movement in said reciprocation, andthe feeding and cutting devices during the retreat in said reciprocation, with means for imparting said reciprocation, essentially as set forth.

7 The combination of simultaneously-reciprocating barb-feeding, barb-cutting, barb-coiling devices, and means for imparting said reciprocation when said feeding, cutting, and coiling devices are timed to operate as folylows, viz: the coiling during the forward movement in said reciprocation, the feeding during the backward movement, and the cutting at the completion of the said backward movement, substantially as set forth.

8. The feed-rolls mounted upon a recipro- -cating carriage, and intermittently actuated by a ratchet and pawl, the latter being connected with the stationary frame, in combination with the carriage and the ratchetand pawl, substantially as set forth.
